ON THE CONSTRUCTION OF BALANCED INCOMPLETE BLOCK DESIGNS [PDF]
Annals of Eugenics, 1939 The articles published by the Annals of Eugenics (1925–1954) have been made available online as an historical archive intended for scholarly use. The work of eugenicists was often pervaded by prejudice against racial, ethnic and disabled groups. The online publication of this material for scholarly research purposes is not an endorsement of those views

Double Arrays, Triple Arrays and Balanced Grids [PDF]
, 2005 Triple arrays are a class of designs introduced by Agrawal in 1966 for two-way elimination of heterogeneity in experiments. In this paper we investigate their existence and their connection to other classes of designs, including balanced incomplete block

Neighbor Balanced Block Designs for Two Factors [PDF]
, 2010 The concept of Neighbor Balanced Block (NBB) designs is defined for the experimental situation where the treatments are combinations of levels of two factors and only one of the factors exhibits a neighbor effect.

A Regular D‑optimal Weighing Design with Negative Correlations of Errors
Acta Universitatis Lodziensis. Folia Oeconomica, 2019 The issues concerning optimal estimation of unknown parameters in the model of chemical balance weighing designs with negative correlated errors are considered. The necessary and sufficient conditions determining the regular D‑optimal design and some new

PBIBDs from weakly divisible nearrings and related codes [PDF]
, 2005 1In [5] the authors are able to give a method for the construction of a family of partially balanced incomplete block designs from a special class of wd-nearrings (wd-designs). In this paper the wd-design incidence matrix and the connected row and column

Statistical Methods to Support Difficult Diagnoses
Diagnostics, 2021 Far too often, one meets patients who went for years or even decades from doctor to doctor without obtaining a valid diagnosis. This brings pain to millions of patients and their families, not to speak of the enormous costs.

Optimal two-level conjoint designs with constant attributes in the profile sets [PDF]
, 2010 We propose a simple strategy to construct D-, A-, G- and V-optimal two-level designs for rating-based conjoint studies with large numbers of attributes. In order to simplify the rating task, the designs hold one or more attributes at a constant level in ...

Deterministic Construction of Measurement Matrices Based on Bose Balanced Incomplete Block Designs
IEEE Access, 2018 Compressed sensing is a novel information collection theory. Compared with the Nyquist sampling theorem, compressed sensing can obtain all the information of a signal with very few samples.
